    kbuild: prepare for moving headers into mach-*/include/mach · 0e7368c6
    Masahiro Yamada authored
    In U-Boot, SoC-specific headers are placed in
    arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that
    directory is created at the early stage of the build process.
    
    Creating and removing a symbolic link during the build is not
    preferred.  In fact, Linux Kernel did away with include/asm-$(ARCH)
    directories a long time time ago.
    
    As for ARM, now it is possible to collect SoC sources into
    arch/arm/mach-$(SOC).  It is also reasonable to move SoC headers
    into arch/arm/mach-$(SOC)/include/mach.
    
    This commit prepares for that.
    If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists,
    a symbolic to that directory is created.  Otherwise, a symbolic link
    to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.
